Is it possible to update BIOS, while running a BIOS which only supports haswell, with a haswell refresh CPU?

My friend built his first PC the other day, but unfortunately he didn't quite check which motherboard he was buying. Basically, he bought a i5-4460 which can't run on a GIGABYTE Z87-D3HP motherboard because the motherboard doesn't have the BIOS version to support it. He has to update it somehow, but nothing appears when he boots the PC up as the CPU isn't yet supported with the old BIOS.

Is there are way he can update his BIOS with the i5-4460 somehow? Can he just click through the whole BIOS flashing procedure (he can flash it through a USB stick on that motherboard) with that CPU, despite not seeing anything (i.e. could the BIOS be running but he can't see anything)? Would he maybe be able to flash it with just a graphics card plugged in (he can't check as he's waiting for a DVI to VGA adapter)?

Last resort, he can always buy the cheapest supported CPU just to update his BIOS (that would be a G1820 I believe).

Any help is appreciated!

    some boards allow doing it and even if you have no cpu

    but cant see it listed as a feature for that board

    it may be possible to buy a pre flashed bios chip cheaper than a cpu to flash with
  2. I think that you'll have to get the G1280, unfortunately. If you want to replace the flash bios chip, then you have to know how to safely desolder the old chip and solder in the new chip.

    I could do that, but getting the chip would probably be quite difficult. Just for the future, what would such a "feature" be called so you can flash the BIOS with a different CPU?

    Resoldering it wouldn't be too bad of an idea, but first he'd need to get a chip like that. If he'd get the CPU, he would probably just resell it anyway which would probably make him lose like £5 so it's not too bad. Thanks to everyone who helped!
  4. called different things by different board makers heres asus one as an example
